CARPET-LINING.

SPECIFICATION forming part of Letters Patent No.4360.757, dated April 5l1887.

Application tiled May 19, 1886. Serial No. 202,666. (No model.)

To all whom it may concern:

Beit known that I, BRADLEY S. BRYANT, a citizen of the United States,residing in Boston, in the county of Suffolk and State of Massachusetts,have invented certain new and useful Improvements in Carpet-Linings, ofwhich the following is a specification.

This invention consists of a carpet-lining composed of a sheet or sheetsor layer of batting or lap of loose brous material inclosed within asheet of paper, the lap or bat of fibrous material being secured to aportion or aWhole of one side of the sheet of paper When in thecondition of a wet pulp sheet, and,a/fter being dried, folded over andupon the bat or lap of fibrousl material inclosing the same and itsedges secured, all substantially as hereinafter fully described.

In the accompanying sheet of drawings is illustrated a carpet-liningconstructed according to this invention- Figure l being a plan View ofthe carpetlining complete; Fig. 2, a cross section on line 2 2, Fig. l;Fig. 3, a plan viewof the sheet of paper before being folded, with thelap secured to it; Fig. 4, a crosssection on line 4 4, Fig.i

3; Fig. 5, a plan View similar to Fig. 3, but with the lap secured to adifferent portion of the paper sheet; Fig. 6, a cross-section on line 66,' Fig. 5; Fig. 7, a cross-section similar to Figs. 4 and 6, but withthe fibrous lap or bat secured to nearly the Whole of the side of thepaper sheet; Figs. 8 and 9, cross-sections similar to Fig. 2,' butshowing modifications in securing the edges of the paper sheet. Fig. 10shows in cross-section a carpet-lining partially folded, with the lap orbat of fibrous material secured to it, as shown in cross-section in Fig.7. Y

In the drawings, A represents a carpet-lining constructed according tothis invention, of which B is the paper sheet, and C the bat of fibrousmaterial.

' In the manufacture of this carpet-lining a paper-machine of any of theusual constructions is used, for which the paper stuff or pulp isprepared in the usual manner of manufacturing paper. After the pulp ismade into a sheet form by thev paper-machine of the required width,it isrun onto asuitable traveling apron, and when of the rightconsistencythat is, before being dried, or in a wet c ondition-the bator lap of the fibrous material,

form of the required width and thickness, is

.then run onto the sheet of paper-pulp longitudinally, and preferablycentrally, as'shown in Fig. 3, and the whole is then passed to andbetween suitable rolls and pressed together, by which the fibers of thefibrous lap or bat will enter into and become mingled and incorporatedwith the pulp sheet, and the water expressed from the pulp sheet. It isthen passed, with its bat of fibrous material, to'and over the usualdriers of the paper-machine, which dries up all the moisture in theiibrousbat and the pulp sheet, and hardens and forms the paper sheet,and the whole is then preferably passed between the usual calender-rollsto give iinish and surface to the paper sheet. This paper sheet, withthe fibrous bat or lap secured to it, is then, at each side ofthelap orbat, folded over and upon the lap or bat, along the edges a of the bat,inclosing and enveloping the bat, and one edge, b, of the paper sheetAoverlapping the other edge, d, at and along the middle of the lap orbat, as shown more particular] y in Fig. 2 in crosssection. The foldedpaper sheet and lap or bat are tlien secured together by three rows ofstitches, j', the iniddie row, g, passing through the lapped edges ofthe paper, the lap or bat, and the middle portion of the papersheet, andone row of stitches between said middle row, g, and each edge h of thecarpet-lining, the stitches passing through all the thicknesses ofmaterial.

In lieu of lapping the edges b d-of the paper sheet at the middle, asshown in Fig. 2, they can be lapped at or near one edge, h, of thecarpet-lining, as shown in Fig. 8; but in such case the bat or lap offibrous material must be run onto the pulp sheet next to one of itsedges in lieu of at the central portion, as shown in'- Figs. 5 and 6,and then the one side Z of the paper sheet turned over and upon thefibrous material along its edge and around the other edge, d, of thepaper sheet, and there the lapped edges of the paper sheet and the batsecured, as shown in Fig. 8, by stitches. In such case it is preferableto secure the several parts together by three other rows of stitches, asshown in said figure.

vwhich has previously been made into a sheet In lieu of lapping theedges of the paper sheet, as shown in Fig. 8, the two edges b d ofthepaper sheet can, after t-he'paper sheet is folded upon thelap, asshown in Fig. S, extend, as shown in cross-section in Fig. 9, a littledistance beyond the edge of the lap or bat and be secured by stitchesfoutside of the bat, as shown in such figure, the other portions of thecarpet-lining being secured by stitches, as shown in said figure, or asdesired.

In Fig. 7 is shown in cross-section the sheet of paper B before beingfolded, but with the lap or bat of fibrous material secured to nearlythe whole of one side of the sheet, leaving a narrow strip or portion,my, of the paper sheet at one edge, d, clear of the lap or bat, as shownin said figure.

The fibrous lap or bat is secured to the paper sheet, as beforedescribed, when it is in the condition of a wet pulp sheet, and afterbeing dried it is folded upon itself,'as before described, to produceany of the forms of earpet-lining shown in the several figures; but inthis ease the lap or bat of fibrous material is also folded upon itself,the side of the bat of the two side portions, n, of thebat lying againstthe same side of the bat of the other or iniddle portion, p. Then foldedas described, it can be secured by stitches, as before described, oronly secured at the lapping of the two edges of paper. The narrow stripor portion m of the paper is left free of the bat to allow the lap of'such edge over the other edge of the paper sheet` when folded, and inmaking the lining shown in Fig. 9 both edges of the paper sheet shouldbe free of the lap or bat of the fibrous material.

In the last manner of attaching the fibrous material to the pulp sheetsuch lap or bat is preferably made of about half the thickness the lapor bat should be for the carpet-lining when completed, as the folding ofthe lap or hat upon itself to form the lining doubles it up and makes itof the necessary thickness.

In lieu of securing the edges of the paper sheet where theylap bystitches, as described, they can be secured by paste or any suitableadhesive material. It is preferable, however,to secure it bystitehes,and also other portions of the lining by stitches, as inlinings having the lap or bat secured to only a portion of the papersheet, as shown in Figs. 3, 4, 5, 6. The portions of the paper sheet notattached to the lap or bat should preferably be secured tothe rest ofthe lining in some form or other; but in the lining formed by having thelap or bat secured to the whole of one side of the paper sheet, as shownin Figs. 7 and 10, the neccssityof securing the several parts together,except at the lap of the edges of the paper sheet, is obviated, as thebat is secured to the paper sheet over its whole surface on one side,and when folded the fibers of the two contiguous surfaces of the foldedlap or bat interiningle and entwine with one another, which practicallymakes one bat or lap within the paper sheet, and thus serves to keep thewhole together and intact. A more or less number of rows of stitches canbe used, or only the one at the lapped edges of the paper.

In making the carpetlining from the paper sheet with the lap secured toit, as shown in Figs. 3, 4, 5, and G, the lap or bat is preferably of awidth a trifle less than the width desired for the lining when finishedto allow for the turning and the lapping of the paper sheet at itsedges. Any fibrous material suitable for the filling of the carpetliningcan be used, and the paper sheet may be made of any suitable material.

A carpetlining constructed according to this invention, having its layeror lap of fibrous material attached to the paper sheet, as described,secures a carpet-lining that 1s closely connected together in itsseveral parts compact and firm, and does not shake apart, and yetretains its requisite pufiness and elas tieity; also, by attaching thepaper-pulp sheet in the paper-machine to only one side .of the fibrouslap or bat the whole can be easily and quickly dried by the driers inthe paper-inachine, and without wrinkling or ronghening the paper sheet.

A carpet-lining composed of two sheets of paper having a lap or bat offibrous material secured to each paper sh'eet when in a condition of awet pulp sheet, and secured together at their edges, being thesubject-matter of a pending application of mine, Serial No. 214,765,such is not claimed in this application.

I am aware it is not new in carpet-linings to secure the lap or bat of'fibrous material to the paper sheet vwhen in the condition of a wet pulpsheet; nor is it new to inclose the lap or bat of fibrous material in asheet of paper.

Having thus described my invention, what I claim isl. A carpet-liningcomposed of a lap or bat of fibrous material inelosed within a sheet ofpaper, the fibrous material being secured to said paper sheet when inthe condition of a wet pulp sheet, and the paper sheet folded over andupon said fibrous lap or bat and its edges secured, substantially asdescribed.

2. A carpet-lining composed of a lap or bat of fibrous material inelosedwithin a sheet of paper, the fibrous material being secured to saidpaper sheet when in the condition of a wet pulp sheet, and the papersheet folded over and upon said fibrous lap or bat, its edgesoverlapping each other and secured, substantially as described.

3.
